I haven’t changed the PCB; the current project is a USB-powered low-voltage board, not suitable for a 220 V AC lithium-battery charger. This needs a new isolated AC/DC charger with constant-current/constant-voltage control, mains protection, and battery-specific charge limits—not simply a 60 V power supply.

Before designing it, I need the battery label or its chemistry, series cell count, and specified full-charge voltage. Also, do you mean 6 A charging current or 6 Ah battery capacity? A battery advertised as “60 V” generally needs a different full-charge voltage, so guessing could damage it or cause a fire.

No design work was performed. Execution stopped because your ACUs ran out.
